基于惯导解算与数字滤波的舰船振荡运动的分离研究
A Separation Method for Ship Swaying Motion Based on SINS Navigation Solution and Digital Filter
摘要
Abstract
Ship swaying motion in six degrees caused by the effects of marine environment ,such as the wind ,will sig‐nificantly decrease the accuracy of on‐board weapon or other devices .Aiming to solve this problem ,a new separation method based on Strapdown Inertial Navigation System(SINS) solution and digital filter is detailedly designed ,which can separate the sawing motion from navigation motion effectively and generate compensation information for on‐board device ,thus in‐crease the accuracy .In this paper ,the definition about instantaneous movement and its coordinated frame are described ,and the high‐pass filter is introduced to remove Schuler oscillation which produced from the inertial navigation calculation in navi‐gation results .The high‐pass filter is designed and achieved ,and simulation results indicate that with SINS solution and high‐pass filter ,the oscillatory motion can be effectively separated .关键词
